INTRAMOLECULAR V V ENERGY TRANSFER OF FREON123 IN INTENSE IR LASER FIELD

Abstract

Freon123 (CF3CHC12 and CF3CDC12) molecules are superexited by the intense IR laser pulse without tail from the TEA CO2 laser, reaching very high exited state. In the dissociation processes, it is shown that the C-C bonds having higher energy in Freon123 were mostly broken under certain experimental conditions, but only a few C-Cl bonds having lowest energy ruptured. The main products were C2F6, and H2C=C=CH2 and it's substitution derivatives. It is indicated by the relationship between the relative yields of productions and laser energy flux that intramolecular V-V energy transfer of Freon123 is nonrandomizational.
